    α-乙酰内酯的区域选择性螺环化
    摘要:
    单环螺环化前体 3a-c 是通过 α-乙酰内酯 6a-c 与甲基乙烯基酮的迈克尔反应获得的 (7)。通过改变反应条件,从 3a-c 中选择性形成 β-氧代(5a-c)和 δ-氧代(4a-c)内酯的任一区域异构体。δ-氧代内酯 4a-c 在碱性(缓冲)条件下在吡咯烷/AcOH 系统中获得。在酸性条件下,环化反应得到 β-氧代内酯 5a-c。通过与通过皂化/脱羧直接衍生自 δ-氧代内酯 4b 和 4c 的醇 10b、c 的光谱相比,副产物 8b、c 被确定为 β-氧代内酯 5b 和 5c 的分解产物。(© Wiley-VCH Verlag GmbH & Co.

  • Preparation of Acyloins by Cerium-Catalyzed, Direct Hydroxylation ofβ-Dicarbonyl Compounds with Molecular Oxygen
    作者:Jens Christoffers、Thomas Werner、Sven Unger、Wolfgang Frey
    DOI:10.1002/ejoc.200390075
    日期:2003.2
    We report the metal-catalyzed α-hydroxylation of a variety of cyclic and acyclic β-dicarbonyl compounds by molecular oxygen. The decisive advantage of this new method is the use of catalytic amounts of the nontoxic cerium salt CeCl3·7H2O in 2-propanol at ambient temperature. Most of the cyclic substrates 4a−4i give high yields of analytically pure products 5a−5i, and the workup procedure is simple
    我们报告了属催化的分子对各种环状和非环状 β-二羰基化合物的 α-羟基化。这种新方法的决定性优势是在环境温度下在 2-丙醇中使用催化量的无毒CeCl3·7H2O。大多数环状底物 4a-4i 产生高产率的分析纯产物 5a-5i,后处理程序是通过硅胶简单过滤。然而,无环二羰基化合物 4j-4p 的化伴随着副反应和分解,显着降低了产物 5j-5p 的产率。提出的机制与实验结果一致,特别是观察到的摄取。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

    Polymerizable compositions comprising a radically polymerizable resin can be polymerized in the absence of a peroxide initiator and other undesirable components. The polymerizable compositions and methods employ a manganese- or iron-containing salt or organic complex and a 1,3-dioxo compound with one or more other components. The polymerizable compositions have better storage stability and reduced gel time-drift.

  • Studies on the α-acetylation of δ-valerolactone and ε-caprolactone
    作者:Jens Christoffers、Heiko Oertling、Peter Fischer、Wolfgang Frey
    DOI:10.1016/s0040-4020(03)00511-8
    日期:2003.5
    The synthetic approach to alpha-acetylated delta-valero- (7a) and epsilon-caprolactone (7b) is reported. While 7a was isolated in 21% yield from the respective iodoester 5a by an alkylation sequence involving transesterification and Finkelstein reaction, 7b was not obtained from 5b but the dimer 8. Also transesterification and olefin ring closing metathesis (RCM) failed to prepare 7b. RCM resulted in the dimeric lactone 10, showing that the formation of 14-membered rings is favored over that of seven-membered rings. A Mukaiyama-type Claisen reaction finally gave alpha-acetyl lactones 7a and 7b in practically useful quantity of about 10 g (62% yield): starting lactones 13a,b were converted to silylenolethers 14a,b, which were acetylated with acetic anhydride in presence of the Lewis acid catalyst TiCl4. However, acetylation depends on the addition sequence of starting materials: if the mixture of Ac2O/TiCl4 is added to 14b, lactone 7b can be further converted to give bis-oxepanonyl ethanols 15a,b. Both compounds 15 were characterized by X-ray crystallography and NMR. (C) 2003 Elsevier Science Ltd. All rights reserved.
